Using the formula (a + b)2 = (a2 + 2ab + b2), evaluate (310)2. |
|
Answer» Given (310)2 We have (a + b)2 = (a2 + 2ab + b2)(310)2 can be written as 300 + 10 So here a=300 and b=10 Using the formula, (300 + 10)2 = (3002 + 2 X 300 X 10 + 102) On simplifying we get (300 + 10)2 = (90000 + 6000 +100) (310)2 = 96100 |
